But we *are* finishing work to standardize DMARC:
https://datatracker.ietf.org/doc/draft-ietf-dmarc-dmarcbis/
...and there is a huge controversy in the working group about what
normative things to say about this, and whether we should say anything
normative at all.

But this is something different; gmail appears to be seriously
overstepping.  I checked the DMARC record for telekom.de (TXT record
in _dmarc.telekom.de), and here it is:
   v=DMARC1;p=none;rua=mailto:dmarc@telekom.de;ruf=mailto:dmarc@telekom.de;

They are publishing a "p=none" policy, which should *not* trigger a
rejection because of failure to authenticate.  Yet gmail is rejecting
it anyway (as if the policy were p=reject).  I will ask my gmail
contact about this.

Barry (chair of the DMARC working group)
